Festo
578406
Plug screw NPQH-BK-G18-P10
The Festo part number 578406 is a standard plug screw industrial component featuring a G1/8 external thread pneumatic connection and an internal hexagon AF 5 mounting type with a nominal tightening torque of 6 Nm at a ±20% tolerance. It operates within a pressure range of -0.095 MPa to 2 MPa (-0.95 bar to 20 bar, -13.775 psi to 290 psi) for compressed air and up to 0.6 MPa for water at 0 to 50 °C, supporting an ambient temperature range of 0 °C to 150 °C. Constructed with a sealing ring on the screwed plug and rated for high corrosion stress (CRC 3), this component supports lubricated operation and complies with NSF/ANSI 169 for food industry use with an NSF C0523185 certificate.
